I I sylvania have invented certain new and use ful Improvements IHBQHtIDg-EDQIDGS, of I vwhich the fOllOWln'g is a specification, ref

' "erence being'had' to theaccompanyingdraw in s.

I latecomrisin amixture of cement and flint whereby the working surfaces of said bar and plate are maintainedroughe'ned and the lastiiig'qualities'tlierebf materially increased.

It is also an object of the invention to" provide a roll having novel and 1mproved' meanswhereby the bars are conveniently" applied and efi'ectivelymaintained in work-' ing position.

The invention consists in the details of construction and in the combination and arrangement of. the several parts of our improved beating engine whereby certain important advantages are attainedand the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as 'will be hereinafter more fully set forth.

The novel features of our. invention will hereinafter be definitely claimed,

In order that our invention may be the better understood, we will now proceed to- 40 describe the same with reference to the accompanying' drawings, wherein:

Figure 1 is a fragmentary sect onal view taken through a beating roll and bed plate constructed in accordance with an embodiment of our invention;

Fig. 2 is an enlarged fragmentary view taken through the peripheral portion of the beating roll and illustrating theanchoring means for the molded slabs or bars and Fig. 3 is a fragmentary sectional view taken longitudinally through a molded slab or bar and its concomitant parts. As disclosed in the accompanying drawings, B denotes a beating roll coacting in a conventional manner with a bed plate P and which roll B and plate P coact in a .well

Interposed between the strips F in a con-- ventional manner are the feeder bars 8 and between which our improved bars or slabs S are adapted to be formed. Each of our improved bars or slabs Sv'is formed of a mixture of cement and flint which is molded on each strip F- between adjacent bars 8 and which mixture is packed in substantially dry. This mixture ofcement and flint affords a bar or slab which does not wear smooth, as'the cement being softer than theflint, allows the small "particles or pebbles of the fiint to project just enough to maintain a roughened surface. In actual prac- 'tice the wearing qualities of this composition is highly desirable, as the composition becomes as hard as the flint itself, so that the slab may be employed for a protracted. period of time.

The bed plate P may be ofany desired type for coaction with the roll B, but this plate P is also formed of a mixture of cement and flint for the same purposes and. advantages, as has hereinbefore been recited relative to the bars or slabs S.

From the foregoing description, it is thought to be obvious that a beating engine constructed in accordance with our invention is particularly well adapted for use b reason of the convenierrce and facility with which it may be assem led and operated,

fication wit out departing fromthe principles' and spirit thereof and for this reason we do not wish-to be'understood'as limiti ourselves to the precise arrangement an a formation of the several parts herein shown ce t as hereinafter, claimed."

in carrying out ourinvention-in practice exe claim:

series of bars forming pockets therearound,

Y the bases of certain of'the pockets having a reticulatedfabric secured thereto but spaced 16 therefrom, and an abrasive slab within said pockets and in which the reticulatediabrics J are embedded.

circumferentially Spaced -fil er strips,- substantially radially disposedbolts directed through said strips, reticulated fabrics disposed over the outer surfaces ofcertain of said strips, bolts disposed through said strips for holding saidfabrics in applied position but spaced relative to the strips, and abrasive members carried bysaid strips and in which the fabrics are embedded.
